Obstacle sensor using Arduino and HCSR04

arduino-sensor-ultrasonico-hc-sro4-01

BuildCircuit has previously published a project on HCSR04 ultrasonic range finder module. You can checkout the article from this link.

Now, we have another article on HCSR04. It is as simple as the previous project.

HCSR04 ultrasonic range finder module: The HC-SRO4 is an ultrasonic sensor which uses sonar to detect objects at a distance of 2 cm to 4 meters.  This sensor is widely used in robotics to build robots that move and should divert or avoid obstacles. You can read more about this module on this article(more…)

Simple ultrasonic range finder using HC-SR04

Description:The HC-SR04 ultrasonic sensor uses sonar signals to determine distance to an object. It offers excellent range accuracy and stable readings in an easy-to-use package. Its operation is not affected by sunlight or black material.However, acoustically soft materials like cloth can be difficult to detect.
